Mattias Hising

Software Engineer

Action-oriented, business-driven and "people first" Software Engineer. 25+ years of experience building products on the web, apps for mobiles, and games for PC, console and mobile. I prefer Open Source over proprietary software. I love products that solve a real problem for users — and I believe the only way to know if you're actually solving it is to measure it.

Available from April 2026

I work with teams that need a senior engineer / engineering lead to steady delivery and improve decisions.

  • What I've Been Building in yetric/cart

    yetric/cart started as a constrained little game runtime. It has turned into something more interesting: a cartridge model, a scene editor, runtime systems, small games to pressure-test the engine, and now a real console-like flow.

  • Everyone Wants AI. Nobody Knows How.

    The gap between AI enthusiasm and AI strategy is where most teams are stuck right now. A meme nails it.

  • I built a Mantine Theme builder

    A visual tool for configuring Mantine themes — pick colors, adjust radius and spacing, and export a ready-to-use theme object.
